# get-lines

Returns the content of a Lua script source file, or the content of the file between the specified lines.

NOTE: For security reasons, you can not get the content of a script unless the script has been loaded by the server. If you attempt to get the content of a script that has not been loaded, the server returns the error "Source file ... has not been loaded".

    /action=luaDebug&command=get-lines[&file=File]
                                      [&first=First_Line]
                                      [&last=Last_Line]
                                      [&session=SessionID]

Type: Synchronous

Parameter Name | Description | Required
--- | --- | ---
`File` | The name of the file that you want to view. You can use an absolute or relative path. Relative paths are relative to the Facebook Connector installation folder. | Required if the `Session` argument is not set.
`First` | The line number of the first line to view. | No
`Last` | The line number of the last line to view. | No
`Session` | Instead of specifying the `File` argument, you can specify a session ID. In this case, the `get-lines` command returns the content of the file that contains the current function. If you set this parameter and do not specify the `First` and `Last` arguments, the server returns the section of code immediately around the current line (7 lines before the current line, and 7 lines after the current line). | Required if the `File` argument is not set.
